The documentation claims that the `scsh' structure provides an
`open-input-file' that is upwardly compatible with the `open-input-file'
provided by the `scheme' structure. This is true, but useless as far as I
can tell. The Scheme48 module system says that it is an error to open more
than one structure that exports the same name, and sure enough, if I open
both `scheme' and `scsh' in some new structure I'm building, the binding of
the name `open-input-file' is unpredictable. Sometimes I get the scsh
version, and sometimes I get the original Scheme48 version.
Of course none of the package/module/structure/interface stuff is
adaquately documented, so perhaps I'm doing something wrong. Here is what
I'm trying to do:
(define-structure utilities (export [...])
I'm only guessing that I'm supposed to be including `scsh' in the list of
structures to open -- nothing I can find in the manual tells me how I'm
expected to do this.
